-This project automates the setup of a development environment for working on Ruby on Rails itself. Use this virtual machine to work on a pull request with everything ready to hack and run the test suites.
+Microsoft now supports running MS SQL Server server and the command-line tool `sqlcmd` on Linux (see https://docs.microsoft.com/en-us/sql/linux/quickstart-install-connect-ubuntu). This document describes how to use a virtual machine for working on the ActiveRecord SQL Server adapter itself. Use this virtual machine to work on a pull request with everything ready to hack and run the test suites, including an instance of MS SQL Server running in the virtual machine. 
+
+This project builds on the [rails-dev-box](https://github.com/rails/rails-dev-box) project with additions to support SQL Server adapter developement.
+
+The VM installs all the software required to run the Ruby on Rails tests suite too. This allows you to run the PostgreSQL/SQLite/MySQL adapter test suites alongside the SQL Server adapters tests. 
+
+The VM uses the Ubuntu 18.04 image as that's the version supported by [Microsoft](https://docs.microsoft.com/en-us/sql/linux/quickstart-install-connect-ubuntu).

 Building the virtual machine is this easy:

-    host $ cd rails-dev-box
+    host $ git clone https://github.com/rails-sqlserver/activerecord-sqlserver-adapter-dev-box.git
+    host $ cd activerecord-sqlserver-adapter-dev-box
     host $ vagrant up
 
 That's it.
 
 After the installation has finished, you can access the virtual machine with
